I have 2 cats and 1 of them has thrown up undigested food twice in the middle of the night. Both of my cats are acting normal should I be concerned?
It could be hairballs. You can increase the frequency of the malt. If your cat continues to vomit or if he vomits more amount, then take him to the veterinarian to rule out pancreatitis or gastritis among other possible diagnoses.
All the best.
